Nokea
_______ is a lytic enzyme released by the sperm.
- A. Hyaluronidase
- B. Trypsin
- C. Helicase
- D. None of the above
Correct Answer: A
Rationale: Hyaluronidase is the correct answer. It is a lytic enzyme released by the sperm to help penetrate the egg's protective layer. Trypsin is a digestive enzyme produced in the pancreas, not released by sperm. Helicase is an enzyme involved in DNA replication, not released by sperm. 'None of the above' is incorrect as hyaluronidase fits the description provided in the question.

Discuss the anatomical/physiological changes in pregnancy under the following: Cardiovascular system
- A. The heart is displaced upward and to the left by the enlarging uterus, cardiac capacity increases, and blood pressure declines slightly.
- B. The heart is displaced downward and to the right, and blood pressure increases.
- C. The cardiovascular system remains unchanged during pregnancy.
- D. Cardiovascular changes include increased peripheral resistance and reduced cardiac output.
Correct Answer: A
Rationale: During pregnancy, the cardiovascular system undergoes changes such as the heart being displaced upward and to the left by the enlarging uterus, increased cardiac capacity, and a slight decline in blood pressure. Choice B is incorrect as the heart is displaced upwards, not downwards, and blood pressure typically decreases slightly. Choice C is incorrect as the cardiovascular system does undergo changes during pregnancy. Choice D is incorrect as cardiovascular changes in pregnancy involve increased cardiac output rather than reduced output.
What is the definition of incomplete abortion?
- A. Part of the products of conception, especially the fetus, is expelled while the placenta and membranes are retained.
- B. All products of conception are expelled, and there is minimal per vaginal bleeding.
- C. The cervix is closed, and the products of conception remain in the uterus.
- D. The cervix dilates, and the products of conception are expelled.
Correct Answer: A
Rationale: Incomplete abortion is defined as part of the products of conception, especially the fetus, being expelled while the placenta and membranes are retained. This is the correct definition, making option A the right choice. Option B is incorrect as it describes a complete abortion. Option C is incorrect because in incomplete abortion, the products of conception are not retained in the uterus, and the cervix may be open. Option D is incorrect as it describes a situation more likely to be seen in an inevitable abortion.
Which of the following hormone ratios is MOST likely to be increased in a patient with PCOS?
- A. Progesterone/estrogen
- B. LH/FSH
- C. FSH/LH
- D. Glucagon/insulin
Correct Answer: B
Rationale: In patients with Polycystic Ovary Syndrome (PCOS), the LH/FSH ratio is most likely to be increased. This hormonal imbalance is a key characteristic of PCOS, where elevated LH levels relative to FSH contribute to the pathophysiology of the condition. Choice A, progesterone/estrogen ratio, is not typically a defining feature of PCOS. Choice C, FSH/LH ratio, is the reverse of what is commonly observed in PCOS. Choice D, glucagon/insulin ratio, is not directly related to the hormonal imbalances seen in PCOS.
What does reproductive health refer to?
- A. Healthy baby
- B. Frequent coitus
- C. Healthy reproductive organs and functions
- D. Longer lifetime
Correct Answer: C
Rationale: Reproductive health refers to the overall well-being of the reproductive system, including both the organs and their functions. It encompasses the ability to have a satisfying and safe sex life, the capability to reproduce, and the absence of reproductive problems. Choice A is incorrect because reproductive health is not solely about having a healthy baby but also includes the health of the individual. Choice B is incorrect as it focuses only on sexual activity frequency rather than the holistic well-being of the reproductive system. Choice D is incorrect because a longer lifetime does not specifically relate to reproductive health.
Which of the following Leopold maneuvers assesses the fetal lie?
- A. Fundal grip
- B. Umbilical grip
- C. Pawlick grip
- D. Pelvic grip
Correct Answer: A
Rationale: The correct answer is A: Fundal grip. Fundal grip is a specific Leopold maneuver used to assess the fetal lie by palpating the upper abdomen to determine the position of the baby's back and presenting part. This maneuver helps healthcare providers understand the orientation of the fetus within the uterus. Choice B, Umbilical grip, is not a recognized Leopold maneuver and does not assess fetal lie. Choice C, Pawlick grip, and choice D, Pelvic grip, are also not part of the standard Leopold maneuvers used to determine fetal lie.
